Who am I?
Coming from the world of discrete mathematics and algebraic logic, I like working on original applications of discrete probabilistic models to Knowledge Representation, Natural Language Processing and related areas in Information Science like Text Mining and Information Retrieval. The goal is to find efficient algorithms to handle discrete aspects of texts like syntax, linguistic rules and underlying conceptual structure.

I am currently a permanent lecturer at the
Institute of Technology of
Avignon in the department of Statistics and Decision Support Systems (StID).
Before coming to Avignon in 2006, I was appointed as an assistant lecturer
first in 2000 at the Institute of Technology 2 in Grenoble,
then in 2001 at the
University Claude Bernard - Lyon 1, and
in 2002 I was nominated as lecturer at the Institute of Technology of Metz.
I'm teaching Computer Science, Information Systems and Data Mining to both under- and postgraduated students
in Avignon (StID
and masters of computer science
and Digital Governement)
and in Lyon (Masters of Applied Mathematics).
These lectures address the following topics:
- Data Bases (SQL 2 and 3, MySQL, ORACLE, PostGreSQL)
- Algorithms and programming (languages C, C++,Python)
- Information Systems (theory in UML, applications based on XML standard and LAMPS
server: LINUX+ Apache + MySQL + SSL )
- Data Mining (R/Python)
- Statistic tests for Computer Human Interface evaluation (Masters only)
- Order and Hierarchical Structures (lattices and logic for data mining - Masters only)
- Graph theory, Discrete mathematics and Formal Logic
- Probabilitytheory and Statistic
- Linear algebra
Extended summaries in French and students notes are available at
My research interests revolve around Discrete Mathematics, Knowledge
Discovery, Natural Language Processing (NLP), Information retrieval and Cultural Heritage.
The phd's I supervised over these topics are listed in theses.fr
Before these projects, I have been working on the theoretical side using algebraic logic formalism:
Organisation of scientific activities
- CLEF MC2 lab that aimed to evaluate microblog retrieval and contextualization.
- CLEF 2018 conference in Avignon.
